“…Furthermore, it was found that the modulus increase for SMP composites containing functionalised graphene was 25 to 30% higher than those containing raw graphene (Yoonessi et al, 2012). In addition, the toughness and flexibility were both found to have been improved (Thakur and Karak, 2013).…”

“…For graphene oxide composites, researchers were able to show various electrical and thermal property increases in polymers containing both the reduced and surface-functionalized versions of the material. In 2012, Yoonessi et al showed that polyimide-graphene nanocomposites can increase the modulus (up to a 2.5-fold change with 4 wt% graphene loading) as well as the onset temperature for thermal degradation (up to T d~5 45 C with 8 wt% loading versus T d ¼ 504 C for the unloaded version) [33]. In this same study, the authors also modified the graphene with imide functionalities to study the properties of composites with graphene incorporated into the main chain (Fig.…”

Shape memory polymers (SMPs) have been the focus of much research over the last few decades. From the novelty of temporarily fixing a threedimensional shape from a planar polymer sheet, to the uses that SMPs are seeing today as softening biomedical implants and self-deploying hinges, this class of smart materials has successfully been used to tackle a variety of biological, electrical, and mechanical problems. However, the properties of these networks are limited by the organic nature of the SMPs. To enhance their properties, researchers across the globe have looked into imparting the desirable properties of inorganic composite materials to these polymer networks. As the field of shape memory polymer composites began to grow, researchers quantified the unique enhancements that came at varying filler loading levels as a result of controlled material interface interactions. Specifically, the incorporation of nanofillers of various shapes and sizes leads to increased internal interfacial area relative to micro-and macrocomposites at identical loading fractions and imparts interesting mechanical, optical, electrical, thermal, and magnetic properties to these emerging nanocomposites. This new class of material, referred to in this review as shape memory polymer-inorganic nanocomposites (SMPINCs), allows a host of new interactions between the smart polymer and its surrounding environment as a result of the ability to control the internal environment of the polymer network and nanofiller. In this work, the reader is introduced to both the methods of preparing these composites and the effects the fillers have on the biological, electromagnetic, and mechanical properties of the resulting composite.

“…Recently, GE has been concerned on the atomic-scale and macro-scale friction behaviors by a lot of scientific researchers. 14,15 There are several main polymer matrix using GE as nanometer packing, including epoxy resin, 16 polyimide (PI), 17 polystyrene (PS), 18 polyurethane (PU), 19 nylon 12, 20 highdensity polyethylene (HDPE), 3 etc. However, to our knowledge, there are few studies about the effect of carbon materials (such as CNTs, GE) on the tribological properties of CF/PTFE composites at high speed.…”

The tribological, mechanical, and thermal properties of carbon series additions reinforced CF/PTFE composites at high speed were investigated. In this work, carbon fiber (CF) filled polytetrafluoroethylene (PTFE) composites, which have excellent tribological properties under normal sliding speed (1.4 m/s), were filled with some carbon materials [graphene (GE), carbon nanotubes (CNTs) and graphite (Gr)] respectively to investigate the tribological properties of CF/PTFE composites at high sliding speed (2.1 and 2.5 m/s). The results reveal that the carbon series additions can improve the friction and anti-wear performances of CF/PTFE, and GE is the most effective filler. The wear rate of 0.8 wt % GE/CF/PTFE was decreased by 50 2 55%, 55 2 60%, 40 2 45% at 1.4, 2.1, and 2.5 m/s compared with CF/PTFE. SEM study shows GE could be helpful to form smooth and continuous transfer film on the surface of counterparts. Meanwhile, GE can improve its tensile strength and elastic modulus obviously. Thin layer structure of GE could enhance the thermal conductivity, which can be helpful to dissipate heat of CF/PTFE composites wear surface. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym.
